IMPIROVEMENT IN FIRE-PROOF SAFES.

Specification forming part of Letters Patent No. 129,286, dated July 16, 1872.

` placed a little distance from the metallic shell so as to leave an air-chamber between them. The space between the mica Walls b b is filled with plaster of Paris, B, after the usual manner of filling iron Walls with the same. The other sides of the safe are constructed as above described for the door, by which construction it is believed that the safe is rendered much more efficient as a tire-proof safe than those now in common use.

I claim as my invention- The employment of mica walls in the con struction of iire-proof safes, substantially as and for the purpose described.
